ELEVATOR.

SPECIFICA'I'IQN forming part of Letters Patent No. 635,499, datedOctober 24, 1899.

Application filed March 2, 1898. Serial NO- 672,282. (No model.)

To all whont it may concern:

Be it known that I, REUBEN J. MELIUS, a citizen of the United States,residing at Bathon-the-Hudson, in the county of Rensselaer and State ofNew York, have invented new and useful Improvements in Elevators, ofwhich the following is a specification.

This invention relates to certain improvements on the elevator for whichLetters Patent of the United States No. 515,781 were granted to me onthe 6th day of March, 1894; and it consists in providing the elevatorwith a chute having a tiltable bottom which is arranged in such mannerin relation to the elevator mechanism that coal or other com moditiesraised by the elevator can be discharged at either side of the latter;and it also consists in providing the guide-floor for the elevator witha series of openings through which the material raised by the elevatorcan be anmatically discharged at different elevations, and providingsuch openings with removable shutters for closing them when saidopenings are not required for use.

In the accompanying drawings, which form part of this specification andwhich are herein referred to, Figure 1 is a side elevation of anelevator embodying my improvements, a portion of said figure being shownin vertical section; Fig. 2, a front elevation of Fig. 1, with portionsbroken away to show underlying parts; and Fig. 3, an end elevation ofone of the elevator-buckets detached from the chain.

As illustrated in the drawings, A designates sprocket-wheels secured toshafts B in the usual manner and provided with horns 0, adapted toengage in endless chains D, which are common to this class of elevators.

E designates open-top buckets secured at stated intervals to the chainsD by the usual means of securing such parts, so that the chains can beflexed, and for that purpose each of said buckets is provided with atransverse rod F at its upper and lower sides, and, as shown in Fig. 1,the uppermost rod serves as a pivot on which a swinging door G is hingedto the bucket E, and the lower edge of said door is preferably providedwith a curved lip 11, which closes over the lower rod,

as shown in Fig. 3, so as to slide freely over the parts on which thebucket moves.

1 designates string pieces which are arranged between the upperand lowersprocketwheels A and on which the chains D are moved. Said string-piecesare connected to gether by cross-ties J to give stability to the frameso formed. The cross-ties J of the uppermost string-piece I are arrangedbelow the outer face of said string-pieces to allow the thickness of theremovable shutter K to lie even with the upper side of the string-piecesJ, said removable shutters forming a guidefioor for the buckets E of theelevator.

L is an open-ended trough which is attachable to the string-pieces Idirectly under each opening M through the guide-floor N. The bottom ofsaid trough is made shorter at each end of the latter than the sidepieces of the trough, so as to form stops for limiting the movements ofa tiltable chute that is carried by the trough L, as shown in thedrawings. In the drawings only one of the openings M is shown uncovered;but several such openings may be provided, and the trough L should beadapted to be attached directly under either of the openings formedthrough the guidefioor N. A chute O, which is tiltable, is journaled ona rod P, arranged across said trough, so as to be at the middle, ornearly so, of the chute, so that when thelatter is tiltedin eitherdirection the depressed end of the chute will take against thecorresponding end of the bottom of the trough L and will be supportedthereby.

The chute O is arranged so that the material raised in the buckets Ewill be discharged from the latter directly into the chute. Then if saidchute is in the position shown by the full lines of Fig. 2 said materialwill pass out of the depressed end of the chute; but if said chute istilted into the position indicated by dotted lines in Fig. 2 thedischarge will occur in the opposite direction from the one justreferred to, and in this manner coal or other material can be dumped ateither side of the elevator at the option of an operative.

The swinging door G should be made to conform to the shape of theperiphery of the rim of the sprocket-wheels A, over which the buckets Eare carried. As shown in the drawings, said swinging door is curved, butwhen polygonally-formed tumblers are substituted for saidsprocket-wheels said doors can be made fiat.

The operation of my invention is as follows: The chute 0 being tiltedinto a required position, the necessary motion is imparted to thesprocket-wheels Ato carry the buckets on the descending part of thechains D into the material to be raised. Thereby the bucketsE will besuccessively filled and moved upwardly by the ascending part of saidchains. As each bucket reaches an uncovered opening M in the guide-floorN the weight of the material in the bucket will force open the door G,as shown in Fig. 1, thereby permitting the contents of the bucket tofallout of said bucket into the chute 0, from whence the material willslide out to the place that is provided to receive it.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. In an elevator, the combination with an inclined guide-floor, N,composed of removable shutters, K, which form closures for openings, M,in said guide-floor; said shutters being supported in placebystring-pieces, I, and cross-ties, J, as herein set forth, of anelevatorbucket, E, having, at its back, a swinging door, G, and adaptedto be moved on said floor; said door being arranged to be opened bygravity while the bucket is passing over an uncovered opening M in theguide-floor, and to close automatically by contact with the closed partof said floor, as specified.

2. In an elevator, the combination of an inclined guide-fioor,N,providedwith an opening or openings, M, formed therethrough, an elevator-bucket,E, havinga swinging door, G, hinged to cover its rearmost side; saidbucket being arranged to be moved on said guidefioor, an open-endedtrough, L, and a tiltable chute, O, journaled transversely between thesides of said open-ended trough, L, whose bottom forms stops forlimiting the movement of said chute in either direction; said chutebeing arranged directly under an opening, M, in the guide-floor, and sothat the contents of said bucket will fall directly into the chute andbe discharged from the depressed end of the latter, as specified.

The combination of a trough, L, having its opposite ends open and havinga bottom that is shorter than the sides of the trough, so as to form astop at each end thereof, and a tiltable chute, O, transversely pivotedat, or near, its mid-length to said trough and arranged to be tilted sothat either end of said chute can be depressed until it takes againstthe corresponding end of the bottom of the trough, as specified.
